Application filed J une 8,1906. Serial No. 320.892.

To all ufl-wm if 712,111/ con/cern,.- Be it known that I, JdHN O. PARKER, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain 'new andv iu'seful Improvements in Paper-Coating Machines, of which the following is a specification. A

In this machine for coating both sides of a running web of paper or other fabric the coating is applied Without immersing the web and without the use of coating-brushes.

The invention will be readily understood from the following description, taken in connection with the accompanying drawings, in which` Figure 1 is a side elevation of a papercoating machine exemplifying my invention; Fig. 2, a plan of a portion of the squeezerolls, and Fig. 3 a vertical section squeeze-rolls and coating-tubes.

In the drawings, 1 indicates the side Aframes of a coating-machine 2, the uncoated web of paper or,ot er fabric coming from the supply-roll to the coating apparatus, as usual;` 3, the coated web of paper on its' way to the polishing and drying apparatus, &c., after leaving the coating apparatus; 4, 5, 6, and 7, carrying-rolls for guiding the paper on its course, the illustrated arrangement of these rolls' being merely typical; 8, a pair of s ueeze-rolls between which the paper runs .a ter being coated; 9, a pair of tubes disposed at each side of the paper as it enters etween the squeeze-rolls, these tubes being longitudinally perforated, so as to direct. jets of Ii uid coating material against the faces of t e paper prior to its entering between the squeeze-rolls, these tubes to L have of the 'squeeze-rolls at )t suitable connection with a supply of liquid coating material; and 10 ssets at the ends iat side of them where the paper enters, these ssets forming dams to limit the end flow o coating material in the channel formed between the squeeze-rolls. The tubes deliver the coating material to the paper, and the squeeze-rolls immediately act upon the delivered coating and even it upon the paper, leaving the vpaper in coated condition ready for the action of the usual polishing devices. While the coating material is delivered by the tubes,

the actual efmaterials, for in the il of the fective coating, or the pressing of the coating to the paper and the evening of it thereon, is done by the rollers. The system is therefore essentially that of coating by means yof squeeze-rolls. While the rolls may be arranged with their aXes horizontal or 'vertical and while the paper may be drawn upward or downward by means of horizontalrolls or in either horizontal direction by means of vertical rolls, the particular arrangement illustrated is by far preferable for most all coating materials, and 1particularly with some ustrated arrangement in lwhich the paper is drawn downwardly p through the rolls just after receiving vthe coating material from the tubes a quantity of coating material may lie in the groove over the squeeze-rolls the sur lus coatin material being held back by t e rolls. T 's arrangement permits of extremely liberal coat- 1. A coating-machine comprising carrying-rolls for guiding the 'web of fabrlc to be coated, a pair of s ueeze-rolls to lengage the opposite sides of t e passing fabric, and a longitudinally-perforatedl jet-tube disposed at the entry side of the squeeze-rolls and adapted to discharge coating material upon the fabric as it enters between the squeezerolls, combined substantially as set forth.

2. A coating-machine comprising carrying-rolls for guiding the web of fabric to be coated, a pair of s ueeze-rolls to engage the opposite sides of t e passing fabric, and a longitudinally-perforated jet-tube disposed parallel with the squeeze-rolls and above their point of contact and adapted-to discharge coating material upon the fabric as it nters downwardly between the squeezerol s.
